JSROLLPANE LARGE

JScrollPane: display a large component within a smaller display area
Adding the component to a JViewport
Identifying the component to be scrolled can be done in one of two ways.
import java.awt.BorderLayout;
import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JScrollPane;
public class JScrollPaneViewport
{
public static void main(String args[])
{
JFrame frame = new JFrame("Tabbed Pane Sample");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JLabel label = new JLabel("Label");
label.setPreferredSize(new Dimension(1000,1000));
JScrollPane jScrollPane = new JScrollPane();
jScrollPane.setViewportView(label);
frame.add(jScrollPane, BorderLayout.CENTER);
frame.setSize(400, 150);
frame.setVisible(true);
}
}

JSCROLL PANE

Add component to JScrollPane
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.FlowLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JScrollPane;
import javax.swing.border.LineBorder;
public class AddingToJScrollPane
{
public static void main(String args[])
{
JFrame frame = new JFrame("Tabbed Pane Sample");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JLabel label = new JLabel("Label");
label.setPreferredSize(new Dimension(1000, 1000));
JScrollPane jScrollPane = new JScrollPane(label);
JButton jButton1 = new JButton();
jScrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
jScrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
jScrollPane.setViewportBorder(new LineBorder(Color.RED));
jScrollPane.getViewport().add(jButton1, null);
frame.add(jScrollPane, BorderLayout.CENTER);
frame.setSize(400, 150); frame.setVisible(true);
}
}

JPANEL

Using JPanel as a container
JPanel components are opaque, while JComponents are not opaque
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class PanelWithComponents
{
public static void main(String[] a)
{
JPanel panel = new JPanel();
JButton okButton = new JButton("OK");
panel.add(okButton);
JButton cancelButton = new JButton("Cancel");
panel.add(cancelButton);
JFrame frame = new JFrame("Oval Sample");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(panel);
frame.setSize(300, 200);
frame.setVisible(true);
}
}
